Clinical Features of Refractive Accommodative Esotropia according to the Age of Onset

ABSTRACT

PURPOSE: To examine the difference of clinical features according to age of onset of refractive accommodative esotropia. METHODS: We retrospectively analyzed the medical record of 52 cases of refractive accommodative esotropia for more than 12 months of follow-up from March, 2000 to December, 2003. The factors we compared were gender, age of first ocular examination, interval from age of onset to first glasses, preoperative refractive error, amount of deviation corrected with hyperopic glasses, stereopsis and associated ocular conditions. RESULTS: Cases were grouped according to age of onset. Fourteen (27%) patients were less than 2 years old., 32 (62%) were between 2 to 4 years old, and 6 (11%) were between 4 to 6 years old 6. the group less than 2 years old showed lower levels of preoperative refractive error than the group more than 2 years old. The younger the age of onset, the lager the deviation angle without hyperopic glasses. There were no differences according to age of onset in gender, interval from age of onset to first glasses, stereopsis, anisometropia or amblyopia. CONCLUSIONS: In refractive accommodative esotropia, the younger the age of onset is, the lager the deviation angle without hyperopic glasses and the greater the deviation can be corrected with hyperopic glasses.
